General Description:
Dimethiconol is a silicone-based polymer known for its smooth, velvety texture and excellent conditioning properties. Structurally related to dimethicone, Dimethiconol contains hydroxyl groups that allow it to form flexible, breathable films on the skin and hair. Typically appearing as a clear, viscous liquid, it is often blended with lighter silicones for ease of application. Dimethiconol is widely used in cosmetics and personal care products for its ability to enhance texture, provide a silky feel, and improve product spreadability. It is available for wholesale and bulk supply, making it ideal for manufacturers focused on premium skincare and hair care formulations
Uses in the Cosmetics Industry:
Dimethiconol is commonly found in:
Hair conditioners, serums, and anti-frizz products to smooth, protect, and add shine to hair.
Skin care products like moisturizers, primers, and anti-aging creams to deliver a soft-focus effect and improve skin texture.
Sunscreens and color cosmetics for enhanced spreadability and water resistance.
Hand creams and barrier lotions where long-lasting film formation and non-greasy protection are required.
Due to its film-forming and conditioning benefits, Dimethiconol is frequently used in both rinse-off and leave-on products across skin, hair, and makeup categories.
Side Effects & Hazards:
Dimethiconol is generally considered safe for use in cosmetics, with a low risk of irritation or sensitization. It is non-comedogenic, non-toxic, and does not penetrate the skin barrier, making it suitable even for sensitive skin types. However, it is not biodegradable, which may raise environmental concerns in eco-conscious formulations. In manufacturing, standard precautions should be taken, such as using gloves and eye protection to avoid accidental exposure, especially when handling concentrated raw material. Storage should be in sealed containers in a cool, dry area, protected from direct sunlight and moisture.

Purity Grade: Cosmetic/Pharmaceutical Grade
Appearance: Clear, colorless to slightly hazy viscous liquid
Solubility:Insoluble in water; soluble in silicones and some organic solvents
Preservation: Typically self-preserving due to low water activity and microbial resistance; preservatives not required in pure form
Storage: Store in a cool, dry place; keep container tightly sealed; protect from heat and direct sunlight
Raw Material Sources: Derived from silicon-based compounds sourced from quartz/silica (sand) and processed through petrochemical intermediates
Manufacture: Synthesized via controlled polymerization of siloxane monomers, followed by end-capping with hydroxyl groupsAnimal Testing: Often available from cruelty-free suppliers; confirm policy with individual manufacturers
GMO:Not derived from genetically modified organismsVegan: Yes; synthetic and mineral-based, with no animal-derived components
Proposition:Generally compliant with California Proposition 65; ensure no impurities (e.g., residual cyclic siloxanes like D4/D5/D6) in final formulation
Warning:May cause mild eye irritation in raw form; avoid contact with eyes; use with appropriate ventilation when handling large volumes
FAQ (Frequently Asked Questions)
1. What is Dimethiconol?
Dimethiconol is a silicone-based polymer used in personal care formulations for its superior conditioning, smoothing, and moisture-sealing properties. Unlike traditional silicones, Dimethiconol is a hydroxyl-terminated silicone, making it more versatile in advanced hair and skin care applications.
2. What is the INCI name and CAS number of Dimethiconol?
CAS Number: 70131-67-8
INCI Name: Dimethiconol
3. What are the key benefits of Dimethiconol in cosmetic formulations?
Enhances smoothness and silkiness in hair and skin products
Forms a breathable, flexible film to reduce moisture loss
Improves spreadability and texture of creams and serums
Adds shine and reduces frizz in hair products
Non-comedogenic and skin-friendly when used in appropriate levels.
4. In which personal care products is Dimethiconol used?
Dimethiconol is widely found in:
Hair conditioners and anti-frizz serums
Leave-in treatments and styling products
Skin moisturizers and anti-aging creams
Sunscreens and BB creams
Makeup primers and foundations
5. Is Dimethiconol safe for use on skin and hair?
Yes, Dimethiconol is considered safe and non-irritating for topical use. It is non-comedogenic, meaning it won’t clog pores, and is suitable for sensitive skin and scalp when used correctly.
6. How does Dimethiconol differ from Dimethicone?
While both are silicone-based, Dimethiconol contains hydroxyl end groups, making it more chemically reactive and often used in blends for enhanced performance. It offers greater film-forming and conditioning abilities compared to standard Dimethicone.
7. What is the recommended usage level of Dimethiconol in formulations?
Typical usage ranges from 0.5% to 5%, depending on the product type and desired effect. In hair serums, higher levels may be used for gloss and frizz control.
8. Is Dimethiconol biodegradable or eco-certified?
As a silicone, Dimethiconol is not readily biodegradable and may not meet strict eco-label criteria. However, it is widely used due to its safety and performance, especially in rinse-off products where environmental buildup is minimal.
